VISE.

SPECIFICATION forming part of Letters Patent N0. 630,530, dated August 8, 1899. Application filed February 28,1899. Serial No. 707,132. (No model.)

To aZZ whom it may concern:.

Be it known that LCLARE ERNST, a citizen of the United States, residing at Bay City, in the county ofBay'and State of Michigan, have invented certain new and useful Improvements in Vises, of which the following is a specification, reference being had therein to the accompanying drawings. 7

The invention relates generally to Vises; and the principal object of my invention is to produce a device of this kind capable of being quickly engaged about the article to be held and which after the said engagement has been effected may be made to clamp the article in a more effectivemanner than has heretofore been attained.

With this object in view my invention consists in the novel construction of a viseand in the peculiar arrangement and combination of the various parts thereof, as'will'be more fully hereinafter described, and shown in the drawings.

Figure 1 is a vertical central section through the vise. Fig. 2 is a section taken on line w as, Fig. 1. Fig. 3 is a section on line y y, Fig. 1. Fig. 4 is a section on line 10 w, Fig. 1; and Fig. 5 is a horizontal section substantially on line 2 2, Fig. 1.

The reference-letter A designates the stationary jaw of the device, which is provided with a suitable base-plate B. This jaw is f urther provided with upper and lower longitudinal bores C and D, which are adapted to receive the supporting-arms E and F, which carry the movable jaw G. The upper supporting-arm terminates at its outerend in the reduced portion H, which extends through an opening 1, formed in the movable jaw, and upon the end of said reduced'portion is de tachably secured a handle, J, by means of which the arm is rotated. In construction the handle comprises the handle proper, a,{ and the head or cap I), having a socket 0 formed centrally therein, which engages over the extension. The head also is centrally apertured at d and is provided with a key (1', adapted to engage with a keyway c, formed in the reduced'portion of the arm, and with a pin f, the function of which will be hereinafter set forth.

Intermediate the jaws of the vise is arranged a connecting-head Kfor the arms, said .headbeing sleeved over the reduced portion of the arm E and having a pivotal connection with the end of the lower armF. The head is provided with an L-shaped extension M, which is adapted to receive a lug or extension 0, formed upon the lower portion of the movable jaw. The opening I, formed in said movable jaw,'is enlargedat'its outer end, as shown at I in Figs; land 5, which allows the jaw to be rocked in a vertical plane,'and likewise to be adjusted laterally to bring the vertical face of the jaw at an angle to the complementary face upon the stationary jaw. The point of connection between the jaw and the head constitutes the fulcrum for the rocking movement of said jaw, and a spiral spring 1?,

sleeved upon a stud 9', is arranged intermediate the rocking jaw and the head for the purpose of maintaining the'former normally in an inclined position, as'shown' in Fig. 1. The means forsecurin'g said rocking jaw in its various positionsof lateral adjustment consists of a clamping-plate Q, which. is

sleeved upon the arm E between said jaw and the handle, and a clamping-lever h, which engages a threaded bolt fc', extending through the lower portion of the'jaw and the 'plate.

The clamping-plate is provided with'a curved slot j, as shown in Fig. 4:, in which the pin f is adapted to engage, limiting the rotary movement of the handle, and likewise the arm with which the handle turns.

' [From the description ofv theinvention as thus set forth it will be observed that the rocking jaw is capable of movenient'freely to or away from the stationary jaw, whereby the jaw members may be made to quickly engage about the articleto' be clamped. 'After the said engagenientis effected the arm onwhich the rocking jawis mounted is adapted to be 1 locked against lateral movement, and the final cated cooperating series of teeth T and U.

movement, a movable jaw mounted upon the The lower arm F is provided in like manner supporting-arm and havinga rocking engagewith teeth, and the bore in which said arm engages is provided with cooperating teeth. Fixedly secured to the upper and lower arms, adjacent to the arm-supporting head, are the gear-segments V and IV, and within the upper arm E is arranged the longitudinal here, which has the threaded portion Y therein.

\Vithin the bore in the arm E is arranged a screw Z, having a threaded port-ion A, adapted to engage with the thread upon the interior of the bore. This screw extends through the apertured head of the handle and is provided at its outer end with an operatinghead 13. 7

From the description as set forth it will be apparent that by turning the handle J the upper supporting-arm E will be partially rotated, and by means of the gear-segments upon said arm and the lower arm I the latter will be likewise rotated, whereby the teeth upon said arms will be moved out of engagement with the teeth within the bores, thus leaving the arms free for lateral movement in either direction. After the rocking jaw is moved into engagement with the article thatis to be clamped and the support locked within the stationary jaw the operator by rotating the head B is enabled to rock the jaw G into closer contact with the article, thereby effectively clamping the same.

\Vhile I have shown and described two armsupports for the rocking jaw, I do not desire to be limited to this construction, as only a single support may be employed without departing from the spirit of my invention.

\Vhat I claim as my invention is 1. In a vise, the combination with a stationary jaw, of a support engaging said jaw for free endwise movement in either direction, a movable jaw mounted upon the support and having a rocking engagement therewith, means for locking the support to the stationary jaw, and an independent operating mechanism for rocking the movable jaw after the locking of the support has been effected.

2. In a vise, the combination of a stationary jaw having a horizontal bore extending entirely therethrough, of a supporting-arm arranged within the bore for free endwise movement in either direction,a movable jaw mounted upon the supporting-arm and having a rocking engagement therewith, means for locking the arm within the bore against lateral movement, and mechanism, separated from and operating independently of the arm-locking means, for rocking the movable jaw.

3. In a vise,the combination with a stationary jaw provided with a bore extending entirely therethrough, and a series of teeth arranged longitudinally within the bore, of a supporting-arm within the bore arranged for endwise and rotary movement, a series of teeth upon the arm adapted upon the rotation of the latter to engage the teeth within the bore to lock the arm against endwise ment therewith, means for rotating the arm, and means for rocking the movable jaw.

4c. In a vise, the combination with the stationary jaw, of a support engaging said jaw for free endwise movement in either direction, a head loosely sleeved upon the support and depending therefrom, a movable jaw fulcrnmed upon the head and having a rocking engagement with the support, means for locking the support against lateral movement, and means for rocking the movable jaw.

5. In a vise, the combination with the stationary jaw, of a support engaging said jaw for free endwise movement in either direction, a head loosely sleeved upon the support and depending therefrom, a movable jaw fulcrumed in the head having a central opening formed therein, said jaw being sleeved over the support and having a rocking engagement therewith, a spring between the head and the jaw acting normally to hold the latter in an inclined position, means for locking the support against lateral movement and means for rocking the movable jaw.

6. In a vise, the combination of a stationary jaw, of a support engaging said jaw, having free endwise movement in either direction, a movable jaw upon the support and having a rocking engagement therewith, means for locking the support to the stationary jaw against lateral movement and means for rocking the movable jaw, comprising a headed screw engaging the support, a cap arranged upon the latter between the movable jaw and the screw-head, and the actuating device for the screw.

7. In a vise, the combination of the movable jaw having a multiple of horizontal bores extending entirely therethrough of a multiple of supporting-arms arranged within the bores for free endwise movement in either direction, a head connecting the arms, a movable jaw mounted upon one of the supporting-arms, and fulcrumed upon the head, said jaw having a rocking engagement with the said arm, means for locking the arms against lateral movement and means for rocking the movable jaw.

8. In a vise, the combination of the stationary jaw having two horizontal bores extending entirely therethrough, and a series of teeth arranged longitudinally within each of said bores, a supporting-arm within each bore arranged for free endwise and rotary movement, a series of teeth upon each arm adapted to engage the teeth within the bores upon the partial rotation of the arms to lock the latter against lateral movement, a connecting-head for the arms in which the latter are arranged for rotary movement, a movable jaw fulcrumed upon the head and having a rocking engagement with one of the arms, means for simultaneously rotating said arms, and means for rocking the movable jaw.
